Yes, overheating is a classic mistake that has been made throughout the history of polar exploration.

However, it is really only a problem when someone is working very hard (like pulling a heavy sled). Even though it's cold outside, vigorous exercise generates a TON of body heat. If you aren't careful, you can sweat a lot while you're working. When you stop working and your body heat dissipates, you can get dangerously cold. The idea is to dress so that you're always a bit chilly, but not really uncomfortably cold. We at PolarExplorers call this "the good cold" and "the bad cold".

Anyone who has ever bundled up and shoveled a bunch of heavy snow knows how easy it is to work up a sweat in cold temperatures. The difference for us is that we can't go inside a heated building and change clothes. We wear essentially the same clothes from the time we set out to the time we complete an expedition.

Why promote a company that accelerates the destruction of such a "pristine environment", as Ms. Aggens herself, describes it? We should leave these areas alone for the scientists to study for the betterment of the Earth as a whole, not provide a playground for the rich so they can trash it. I am not too impressed, but they sure seem happy with themselves.

A reply from Dana with PolarExplorers.com: "Global warming IS changing the Arctic faster than any other part of the planet. This is something we take very seriously and we consider it our responsibility not to be "tourists" but rather to be "ambassadors" to this incredible place that has no voice of it's own. We are in the vicinity of the North Pole for a period of three weeks on average each year, traveling by ski or dogsled most of the time, yet, we spend the rest of the year talking about the expeditions, educating students & teachers and others about the polar regions, and inspiring people from all walks of life to minimize their impacts on the planet. We think it is a vital aspect of what we do and why we do it. These expeditions are not limited to the wealthy; each year we have team members who pay for their expeditions with hard-earned sponsorships after years of planning and preparation. We also have team members who perform climate-based research on the expeditions. We are proud of our teams and the collective work they do to educate people about the polar regions and global warming not to mention the attention they bring to dozens of other deserving charities that benefit from the expeditions."
